[OFF TOPIC] Socket programming via C++

[Anon]

hi all,

first of all, i do apologize for this off topic question. this forum is frequently visited one and i thought it would be a good idea to ask for help.

i want to develop a "CGI" web-mail application using GNU c++. it will connect to a POP3 server residing in a UNIX machine with user authentication. user will her/his mailbox in browser and also will be able to send, delete, read mails.

so here is the question. what should i do? can anyone offer me a web site? i have some information about how to connect via sockets but unfortunately what i dont know is how to implement e-mail operations using C++.

thnx,
kazmanot.

Well,
I was gonna send you a small list of socket programming how tos'...
but seems you have that covered.

I believe you would just output your commands to the socket, since sendmail is a forcked process server that will spawn a child to handle your request, you should be able to interface directly to it and issue your commands... so try it via telnet.
